Tickets for the Denver Art Museum’s “Becoming van Gogh” are in high-demand as the blockbuster exhibit enters its final hours this weekend.

The unlucky few who did not purchase tickets before the show sold-out January 7 are begging friends, calling in favors and turning to the Internet for help.

On Craigslist, there’s a small but eager bit of asking going on, with people offering up to $100 for tickets that originally sold for $25 each. There doesn’t appear to be much of a supply though. Most of the folks I contacted said they got few or no responses. Nobody reported any serious gouging.
